A Diminished Chord

On Monday, I was working on a new piece with an 8-yr-old.  We'd already sorted out the second fingers.  A little phrase kept repeating itself, C-A-F# (2 - open - 2).  I said that could form a chord, and had her play the C while I played the A and F#.

Me: What do you think it sounds like?
Girl: Umm...
Me: Do you think it sounds happy?
Girl: Not really.  But it's not really sad, either.  More... just... squished.
Me [smiling]: True... Do you think it sounds spooky at all?
Girl [squishing up her face, in that 'what is my teacher on about?' look]: Ah... I guess...

One thing I enjoy about teaching, is the new perspective brought to musical theory.  Having had ideas and concepts drilled into my brain for years, hearing new ideas from someone new to the concept is refreshing.
